hello I have a question there is a cat in my house he play`s fine and no behaviour issues but when our cleaner comes in he strikes out at her for a random reason.
He probably feels threatened by something she does. I'm guessing he's a slightly nervous cat anyway - sharper/faster movements, the smell of cleaning products or things like vacuum cleaners or dusters on sticks could easily be enough to put him on the defensive. It might be a kindness to both of them to put him somewhere quiet where he'll be left in peace when your cleaner comes.
